Avoid processing toolnames with same name but different capitalization

[smuzaffar]

While testing cms-sw/cmsdist#9042, I noticed that PR tests script assumes that some tools were removed and tries to rebuild nealy full cmssw during PR tests. This is because some toolfiles have different capitalization but they point to same tool/package (e.g OpenBlas and openblas). This change should avoid such cases for CMSSW releases with SCRAM V2
